I have created a masterchannel on my network.

I am trying to setup Hyperledger Explorer for the created fabric network. I have also updated the config.json based on the created fabric network.

I got the successful build.But it fails to start the explorer application.

I got the follwing error.

**************************************************************************************
Error : Failed to connect client peer, please check the configuration and peer status
Info :  Explorer will continue working with only DB data
**************************************************************************************

(node:10952) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead
<<<<<<<<<<<<<<<<<<<<<<<<<< Explorer Error >>>>>>>>>>>>>>>>>>>>>
Error :  [ 'Default client peer is down and no channel details available database' ]
Received kill signal, shutting down gracefully
Closed out connections

I have provided tls as false and updated grpc. And also the network is up on specified ports.

Help is appreciated.

Paths should be set using the full path /home/user/yourPath instead of the shortcut ~/yourPath.

Anyway, remember always to check the app logs and not just the console since sometimes they show much more information.
